NOTE: Due to varying torque values, one of the following two situations may
occur: 1) The outer piston, diaphragm and inner piston remain attached to
the shaft and the entire assembly can be removed from the center section
(Figure 10a); 2) The outer piston, diaphragm and inner piston separate
from the shaft which remains connected to the opposite side diaphragm
assembly (Figure 10b) . Repeat disassembly instructions for the opposite
liquid chamber . Inspect diaphragm assembly and shaft for signs of wear
or chemical attack . Replace all worn parts with genuine Wilden parts for
reliable performance . Rubber/TPE are not available .
